Where do you usually charge?

Charging losses system default
Energy lost between the socket and the battery (cable, AC/DC conversion, battery management), applied on top of your driving consumption. This is set to a standard 10% and kept fixed so every comparison uses the same assumption.
Maintenance & wear
Defaults are realistic Indian ownership assumptions — every figure is yours to edit.
Annual service & consumables ₹/yr
Repair reserve ₹/yr
Service & consumables bundles oil/filters, coolant, and routine parts. Repair reserve covers unexpected fixes.

EVs typically see lower brake wear from regenerative braking — this is an estimate, not a guarantee.
Long-term battery replacement reserve (optional)
▾
This is an optional long-term reserve, not a prediction that your battery will need replacement. It is excluded from your main results unless you switch it on below.
Replacement estimate ₹

Tyre replacement cost ₹
Expected tyre life km
Annualised automatically from your driving pattern: (annual km ÷ tyre life) × replacement cost. Same tyre economics applied across all three cars unless you know otherwise.
Insurance & fixed costs
These apply across all three cars for a fair comparison. Toggle off anything that doesn't apply to you.
Annual insurance ₹/yr
Road tax / registration ₹/yr, annualised
FASTag / misc road expense ₹/yr
The costs people usually forget
Switch each one on and set a value — or leave it off if it doesn't apply.

How we calculated this▾
Petrol / Diesel
Annual fuel cost = annual km ÷ real-world mileage × fuel price, split city/highway.
EV
Annual charging cost = energy used (kWh) × (1 + charging loss) × blended home/public electricity price.
Tyres
Annual tyre cost = (annual km ÷ expected tyre life) × replacement cost.
Monthly cost
Annual cost ÷ 12.
Cost per km
Annual cost ÷ annual km.
Note: Results are estimates based on the information you entered. Actual costs vary by vehicle, driving style, traffic, fuel/electricity prices, service history, tyre wear, insurance premiums and local conditions. Company mileage/range figures may differ significantly from real-world usage. Fuel and electricity prices are user-editable assumptions and are not live prices.
